Tropical insular ecosystems face escalating, cumulative impacts of land‐ and sea‐based ecological threats that jeopardize the long‐term sustainability of their native communities. This joint vulnerability is epitomized by reef island seabirds, which are exposed to reef decline and coastal erosion driven by climate change, reduction in prey availability, human disturbance, and predation by invasive non‐native species. Using sit...

Aim Human land use shapes landscapes and threatens avian biodiversity, yet its interaction with altitudinal gradients and the consequences for the assembly of long‐distance migratory and sedentary bird communities remain poorly understood. Location Southern France. Taxon Avian breeding communities. Method We examined the changes in the migratory–sedentary ratio (the relative proportion of migratory versus sedentary species) in...

Aim Understanding the relative influence of past and present environmental and anthropogenic drivers on biodiversity is crucial for predicting future biodiversity trends. We assessed how past climate stability, present climate, habitat characteristics, disturbances (fire and herbivory), and past and present land use shape current functional and phylogenetic diversity across multiple taxa. Location Euro‐Mediterranean forests. T...
